不同窗帘材料对川西地区供暖房间的热作用影响分析*
Thermal effect analysis of different curtain materials on heating rooms in western Sichuan
摘要：
基于康定市某居住建筑，根据其外窗传热过程建立了外窗得失热量和夜间冷辐射计算模型，理论计算结果显示，由于窗帘的调控作用，房间平均净得热量可增加20%，采用绒布和镀铝膜材质窗帘相比于无窗帘工况，外窗夜间辐射换热量可分别降低43%和65%。理论与实测数据表明，采用不同材质窗帘可提升室温1～3 ℃，窗帘调控对房间温度提升和室内热环境改善具有显著作用。
Abstract：
Based on a residential building in Kangding city, establishes the calculation models of heat gain and loss of outer window and cold radiation heat loss at night according to the heat transfer process of outer windows. The theoretical calculation results show that due to the regulation and control of curtains, the mean net heat gain of the room can be increased by 20%. Compared with the curtainless condition, the radiation heat transfer of the outer window with the curtains made of flannelette and aluminized film materials at night can be reduced by 43% and 65%, respectively. The theoretical and measured data show that the indoor temperature can be raised by 1 ℃ to 3 ℃ using curtains of different materials, and the regulation of curtains plays a significant role in the improvement of indoor temperature and indoor thermal environment.
